Adds a Global flags subsection to CLI Reference (covering --verbose,
--proxy, --user-agent, --obey-robots, --v8-flags) and a Tuning V8
section with the OOM-on-large-pages motivating example, so users
hitting JavaScript heap out of memory can find --v8-flags from the
use-case side rather than only from --help.
Closes#152. Depends on #131.
Fixes#117. Adds an `Original` variant to `--dump` that streams the raw
HTTP response body verbatim to stdout (or `--output`), bypassing the
browser/JS/DOM stack entirely. Useful for binary payloads (jpg, png,
fonts) and any non-HTML resource where parsing through the DOM layer
would corrupt or discard data.
The new path uses ObscuraHttpClient directly, honours --proxy and
--user-agent, and writes bytes through tokio::io::stdout so binary
payloads (including embedded NUL bytes) round-trip cleanly.
The current ubuntu-latest Linux release can require a newer glibc than common LTS servers provide. Pinning the x86_64 Linux release job to Ubuntu 22.04 keeps the prebuilt binary compatible with glibc 2.35+ environments while leaving macOS and Windows release jobs unchanged.
Also document the Linux LTS compatibility target in the install section so users understand why the release runner is pinned.
